Problems solved by technology

As a surge protector for protection against indirect effects of lightning, it is difficult to meet the requirements in some occasions due to insufficient power of existing devices and other reasons.
[0006] Due to the high distance between thunderclouds and the ground, it is inconvenient to measure directly; the parameters of lightning are difficult to accurately simulate in the laboratory. These have affected the development of research on lightning energy storage and utilization technology and lightning protection technology, and many technical problems have not yet been resolved.
